] ) : intGet the byte length of characters which can be included on one line of the specified width.
textThe text to measure.
widthThe width of the line.
wordwrap
When this parameter is set to TRUE the function "emulates" word
wrapping by stopping after the last full word (delimited by whitespace)
that can fit on the line.
